1 Claim. (01. 43*) The invention relates to fishinglines', and has for its object to provide a device of this kind chambered and formed from a non-absorbent.

material and sufiiciently buoyant to fioat on the surface of the water during a fishing or casting operation. v

A further object is to form the fishing line from a thermo-plastic material, such as Nylon or Permalon, flexibility for casting purposes and is also.non-, absorbent, thereby obviating the present diflia culty and time involved in oiling, and afterwards wiping conventional silk lines.

A'further object still is to provide a transparent or translucent iioatable fishing line which will reduce shadows to a minimum when float- --A still further object line from a fuseable material, the ends of which can be easily sealed by the application of heat, and av smooth line which will easily reeve through fishing rod eyes during a, casting or reeling-in operation.

with the above and other objects in view, the present invention resides in the combination and arrangement of parts as hereinafter set forth,-

shown in. the drawing, described and claimed, it being understood that'changes in-the. precise embodiment of the invention may be made within the scopeof what is claimed without depart-, ing from the spirit of the invention.

In the drawing:

Fig. 1 is a side elevation of andshowing in perspective the tip end of a cast i s.

Fig. 2 is a longitudinal sectional view through the line, showing theends sealed, and,

Fig. -3'is a perspective view of. the line end, showing the method of sealing the same by the application of heat. r 1

Referring to the drawing, the numeral t desig which has sufiicient strength and to form the tubular the line; showing the same floating on the surface of the water been found that a line so formed has suflicient strength for fishing purposes and suflicient flexibility for casting and reeling purposes. It has also been found that by forming the line from a transparent material shadows are reduced 'to 'a minimum, as the light rays will pass "therethrough, and the line will not easily tangle f or knot.

The ends 4 of the line are preferably sealed as at 5, and this sealing is accomplished by a fusing operation, shownin Fig. 3, through the mediumof a flame 6 from a conventional form of match 1, therefore it will be seen that the fisherman can easily repair the line when necessary, either when wading in the stream or in any other desired place.. The line is provided with a conventional form of fly 8 and the usual leader (not shown) is interposed between the end of the rod ll.

line and-the fly, said line being threaded through the usual rod tip 9 and rod eyes l0 carried by the line will easily feed through the rod eyes ll withlthe minimum amount of friction. At the present time silk lines are used, as well as enameled silk lines; however, these are expensive and require much care and have a relatively short life; whereas applicant's line has the strength and flexibility necessary for fishing purposes and incident to its chamber is lighter than water, therefore will float, and incident to its transparent character will reduce shadows to a minimum,whichis ,an advantage in trout fishing. Being formed from a non-absorbent material, it will not be necessary to use a line dressing or to dry the line after fishing.

nates the line which isformed from a transparv,

ent non-absorbent material, for instance Nylon or Permalon, or other similar thermoplastic material having a tensile strength not less than 20,000 pounds per square inch which is flexible and is formed with an air chamber 2 therein. The line maybe formed by an extruding process and thechambe; 2 is sufliciently large so the line, incident to its buoyancy, will float on the.

surface of the water 3, shown Fig. 1. It has 7 From the foregoing, it will be obvious that I have perfected a simple, practical, and economical, buoyant fishing line, which can be readily manufactured, which is non-absorbent, requirno or wiping after use, and'which can be easily quickly sealed.

y The invention, having been set forth, what is claimed as new and useful is: a

A fishing linecomprising a single tubular strand formed from a thermoplastic material having: a tensile strength of at least 20,000 pounds per square inch, the specific gravity of the said tube and gas therein being less than that of water.
